I have some Core memory from a guy who worked at Four Phase. They're made by
Fabri-Tek and he remembers these being used in some IBM system - the best he
can remember. The really cool thing about this is that it's assembled in a
way where it folds up. I have some pics at the links below. I'm hoping
somebody might know what system this came from. I also have closeup pics of
the board, serial, and part numbers too. Then maybe I can find a manual for
this. With some luck and some hacking, I can then wire an interface to this
for my homebrew PDP-8.
